The Gulf stock markets, with the exception of Qatar and Oman, made substantial gains on Tuesday as blue chips rallied. The Kingdom's Tadawul All-Share Index rose 1.17 percent to 6,017.66 points, its sixth advance in seven sessions. SABIC, the market's benchmark, posted the biggest increase on Tuesday among the most active companies, with the price at SR67.75. In Kuwait, the benchmark climbed 0.8 percent to 7,681 points, its ninth rise in 10 sessions. In Bahrain, the measure climbed 2 percent to 1,633 points. In Dubai, the measure climbed 1.2 percent to 1,672 points. In Abu Dhabi, the index was almost unchanged, edging up 0.01 percent to 2,614 points. In Qatar, the index fell for a second day, dropping 1.3 percent to 6,419 points. In Oman, the index fell 1.7 percent to 5,329 points, taking its losses to 5.1 percent since Sunday's 17-week closing high. Most Gulf markets have been rising since mid-March and the rally is likely to continue in the short-term, analysts say, but a correction will be likely if global equities retreat. The Saudi index has made the largest gains regionally this year, rising by 25 percent, while the Kuwait, Qatar, Oman and Bahrain benchmarks are all in the red. __
